Question

My hometown used to be small village with	76．
tree all around. Just outside the village , there was a	77．
river. The river was much clean. Many people enjoyed	78．
boating on the river. Although there were no tall	79．
buildings and people were poor, but they lived a simple	80．
but happy life.
In the past ten years, my hometown changed	81．
a lot. People no loner lived in small houses. Instead,	82．
they live in tall buildings. Supermarkets or factories	83．
can be seen everywhere. But we now have less trees, and	84．
the air and water is polluted. In order to live a better life,	85．
we must do something to protect the environment.
